Rails - Mar 2006 - Radio Button Tag and hash @Params.

Hi,

I''ve a little problem using the Radio Button Tag.
I use the " @prove=MODEL.column_names() " to keep attribute names of a
table. After
i used this code to select a attribute subsets of them :

<% i=''0''%>
<% for @obj in @prove %>
<% @key='':key''+i%>
<%= radio_button_tag (@key,@obj) %>
  <% i=i+''1'' %>
  <% end  %>
  <%= submit_tag ("calca") %>
  <%= end_form_tag %>

But when i come back to the controller, it''is impossible select the 
right radio button value with the code :

 @result=@params[@key];

The compiler don''t understand the Hash key that i used!.
The compiler want to use something such as: radio_button_tag (:key,@obj) 
;

Some ideas?

try
<% @key=''key''+i.to_s%>
or simply
<%= radio_button_tag (''key'' + i.to_s,@obj) %>

also I guess ''0'' and ''1'' need to be replaced
to 0 and 1 (no apostrophes)
otherwise you will get 0, 01, 011, 0111 etc. hashes
